To all 'whom it may concern:

-Be it known that I, JOHN T. H. PAUL, a citizen of the United-States, residing at'Chicago, in the county of Cook and State of 5 Illinois, have invented a new and useful Improvement lin Pasteurizing Apparatus, of which the following is a specification.

This invention relates to an improvement in the tvpe of pasteurizing machine in which L0 a plurality of tanksare employed for containing sterilizing'g Water at different interchangeable temperatures, and into which is introduced the material to be treated (in bottles or other forms of packages), to be subjected in each compartment to thesuccessive temperatures required in the practice of pasteurization.

The primary obiect of the invention is to render the machine, after it has once been 2o started, -thoroughlyautomatic throughout a complete run, so that no manipulation or' attention shall be required on the part of the operator, except for introducinginto and taking -out of the tanks the material under This and other obiects are acthe accompanying drawings, in which Figure 1 is a diagram of the entire machine; Fig. 2, an enlarged broken view showing thesteam-jet device in section; Fig. 3,

Four tanks are shown and are denoted as `W, X, Y, Z', respectively, though the number employed is not material'to the invention. The preferred construction of the tank is that illustrated in Figs. 14 and 15. It involves a continuous body 35, preferably of boiler-iron, for the entire series, bent to U-shape in crosssection,with end-heads flanged and riveted in place through the flanges to the sides and base of the. body, in which the similar com.

artments are'formed each by two partitions 36, 36 like the heads and similarly fastened in place in spaced relation to each other to form the overflow chamber 37 having openings 38 in the upper-end portions ofthe pai'- titions. Each overflow-chamber contains a discharge-opening 39 in its base covered by a -shield 40, and these shields are connected by valve 43 connects at its discharge-end with the pipe 41 andV communicates with the tanks, through their bases, by branches 44, each branch containing a shut-off valve 45;

is reinforced about its and the pipe 42 contains a shut-off valve 46 near its discharge-end. 'lhe series of tanks upper edge with angleiron forming a seat along the sides for a track 47 on which to run a gauntree indicated at 48, Fig. 1, oi' any suitable'construction, for raising out of and lowering into the tanks, racks 49 carrying crates (not shown) supporting the material to be treated, which, for the purposes of the present case, may be considered to be beer in bottles.

lhe gist of the invention consists in controlling the ltemperatures in the different tanks through the medium of a single valvedevice of the preferred construction, hereinafter described, which is automaticall T set at required intervals for the various purposes by suitable mechanism, that shown for the purpose involving the following-described construction and combinations of parts: An electric motor, conventionally illustrated at 50 in Fig. 1,has its armature-shaft geared to a pump-shaft 51, common to three centrifugal pumps 54, 55, 56 of. ordinary or anyl suitable. construction. The pump -shalt drives, through the medium of a train of reducing-gears 57, a shaft 58 carrying on one end a miter 59 meshing with a similar miter 60 on the lower end ofa vertical shaft 61 for operating the aforesaid valve-device. On the opposite end of the shaft 58 is provided an alarm-device 62 ('lfigs. 12 and 13), comprising a gong 63 supported on a stud 64 upon a bracket 65 through which the shaft 58 passes, the bracket being adapted to be secured to any convenient stable support on the stud is rotatably mounted a gear-wheel 66 meshingwith a pinion 67 on the shaft 58 and carrying a segmental ratchet 68, With the teeth of which engages a pawl 69 fulcrumed on the bracket and carrying on its free end a hammer 70 for sounding the gong during alternate rotations of the shaft by the tripping action ofthe ratchet upon the pawl.

The gear '58 a.of the reducing-train which is carried by the shaft .58 is loose thereon to avoid rotation of the shaft except at predetermined intervals by engaging therewith said gear through the medium of a clutchdevice71 a suitable construction of which is illustrated in Figs. 5 to 9, inclusive. A sof lenoid-magnet 72 supported in a bracket 73 has suspended trom the armature 74 on its cores 74a a link 75 which has a releasable hook-connection at 76 with a spring-pressed, vertically movable trip ing-pin 77 working in bearings on the braclet, on on'e of which bearings is ulcrumed `a lever 78 having a link-connection 79 with the hook-link for a purpose hereinafter described.; the trippingpin carrying on its lowenend a cam-shoe 80. On one -tace ofthe ger.' ff the train 57 which is loosely mounted on the shaft' 58 isprovided a` 81 having confined in it at one end of a circular recess 82 concentric with the I disk, a transverse stationary clutch-pin 83 terminating in a -stepped head 84 to engage i'with a si ar head 85 on a spring-pressed pin 86 forming the other clutch-member reciprocably coniined in a-transv'erse bearing in a head 87 about a hub 88 rigidly secured upon the shaft, the pin 86 containing a notch 89, rounded at its outer side and lying in the path of the shoe 80,- which normally bears against an annular flange 90 rovided about the head 87 concentrically with its hub. To energize the solenoid, it is contained in a branch 91 of the motorcircuit 92. This branch also contains an electric switch 93 and a clock 94 carr 'ng on its hour-arbor'95 (Figs. 19 and 19a) a disk 96 rovided about its periphery with irregularlly spaced camsurfaces, the three shorter ones 97 of which correspond in length and terminatev in shoulders 98 and alternate withthe longer cam-surfaces 99, which correspond in length and terminate in vshoulders 100. A springpressed pivotal contact-finger 101 bears against the periphery of the disk, and a relatively shorter spring-pressed pivotal contact-finger 102, included with the other in said branch-circuit, also bears against the said periphery and is curved at its free-end, where it carries a laterally-projecting stud 103 extending into the path of the iinger 101. With the switch 93 closed, the clock, in running, turns the disk 96, whereby each time the shorter-finger -102 clears a shoulder its stud 103 contacts with the longer finger 101, just before `the latter clears the same shoulder, to close the circuit,.the closure being maintained only momentarily until `the longer finger clears that shoulder, when its spring retracts it from the stud 103 to open the circuit.. Each circuit-closure, energizes the solenoid to raise the pin 77 and permit the clutch-memberv companion-member 83 and thus cause the continuously rotating motor 50 to rotate the shaft 58 to the extent of a complete revolution. At the Vbeginning ofethis revolution the circuit is opened at the'disk 96 tordeenergize the solenoid and permit the springpressed shoe to bear against the flange 90 until, in the rotation 'of the gear 57 the pin 86 is brought to the position wherein its notch 89 registers with the cam-shoe 80, whereupon the engagement of the notch with the shoe forces the clutch-member 86 away and disengages it from the member 83 `to unclutch the shaft 58 at the end of the complete rotation thereof.

' he steam-supply for heating the water in circulating from each tank back to the same tank is introduced through a pipe'indicated at 104 in Fig.

lentering; at "107 'm a suitable water-heater, the preferred type of whlch 1s that of a jet-pump device 108 86 to engage with the n l v and containing a shutof`t` valve 105 and a steam-gage 106. the steam and performing its function 5 pressing the diaphragm 25 valve-chamber 122 in the casing,

. 40 admission of air pressure 55 cap 130a (Fig. 2) having its valve-stem 109 carried by a spring-supported diaphragm 110. The jet- .pump coperates with the centrifugal pumps for circulating the water. As means for devalve of the jet-pump', an air-pressure controlling-device is provided, indicated at 111 in Fig. 1 and shown 1n detail in Fig. 4. It

comprises a casing containing a vent-opening 112 anda standard 113 containing a central Huid-passage 114 having its upper end coveredby a diaphragm- 115, and a pipe 116 leading from its opposite end: on this standard is fulcrumed between its ends a lever 117 l to bear at one end against the diaphragm,

and in the opposite end of which works a setscrew 1 18 carrying above the casing a pointer 119 movable over a dial (not shown) in a ,glassecoveredbox 120 on the casing; this setscrew, which is accessible for adjustment, on

-removal of the box-cover, for regulating the bearing-pressure of the lever 117-against the diaphragm, bears against the upper end of a vertically-reciprocable rod 121 working in a the rod being confined against a ball-valve 123 supported against its scat from underneath by I a spring 124 supplemented by air-pressure from any suitable source 0 ted through, a pipe 125 leading into the base (not shown) admit'- cf the valve-chamber, from one side of which near its upper end it communicates through a pipe 126 with the casing of the diaphragm 110., The pipe 116 connects the fluid-passage 114 with a thermostat-device 127 (F ig.-

. 3), containing alcohol or other suitable tiuid expansible and contractible under variations inv temperature to. actuate the diaphragm 115 to work the ball-valve 123 to regulate the through the pipes 125 and 126 against the diaphragm 110 and thereby cause the valve of the jet-pump to regulate the flow of steam through it in accordance with the requirement in heating the circulating water, to which the thermostat 1s exposed in its position on the main valvedevice, being secured to the casing thereof by a T-coupling 128 in which the thermostat extends.

The main'valve-device 129, as illustrated in detail iniFigs. 20 to 26, inclusive, involves the following construction: The valve-casing 130, which is best 'formed in the general cy lindrical shape illustrated, and is closed by a at thebottom and by a gland 130b at the top forming a stuffing-box, has formed upon it at equal distances apart about its circumference vertical passages 131, 132, 133 and 134, each divided by a transverse partition'135 midway between its ends into an upper and a lower section. Four of these passages are shown, one for each tank, but the number thereof required to be j .-ovided will, in each instance, correspond with the .number of tanks employed in the aapp ara-tus,

110 to close the An opening 136 is provided in the upper section of the passage 131, its lower section 'tontaim'ng a' similar opening 137; the passage 132 contains the similar openings 138 and 139, respectively, in its upper and lower sections, similar openings 140 andv 141 are l rovided, respectively, Vin the upper and ower sections'inthe passage 133, and simi- I lar openings 1.42 and 143 are provided in the i upper and lower sections, respectively, of the passage 134, ln a vertical series along the casing between the chambers 132 and 134 are provided the six openings numbered, in' their order from to to bottom, 144 to 149, bothinclusive. Fig. regarded 'as a section taken through any one of these six o enings. The hollow valveplug 150, whic fits rotatably inthe casing and is closed at both ends, carries on a stem projecting from its upper end a gear-Wheel 151, with which meshes a pinion to be rotated by the shaft 5S. The astportioned for the purposes of` the apparatus each complete rotation of the shaft to turn the plug through one-eighth of its complete rotation. The valve-plug is divided at uniform intervals by horizontal partitions into a vertical Aseries of six chambers lnumbered from 153 to 158, both inclusive. Each of 'these chambers contains a circumferential series of ports 159, those in each chamber occupying a plane" opening in the vertical series thereofin the casing, so that in every position of the plug each chamber therein communicates with the respective casing-opening. As shown in Figs. 25 and 26, each vertical passage on the `tical series of six ports, each registering with an adjacent chamber in the valve plug. The chamber 1.53 contains a port 1 60 in the plane of the uppermost ports in the inner walls of said passages; the chamberv154 co-ntains a port-161 in the plane of the next lower ports in saidA inner walls; the chamber 155 contains two similar adjacent ports'162, and also, adjacent to each other, two similar 1by-pass ports 163, in the plane of the next lower ports in said inner walls; the chamber 156 conta-ins ports 164 andby-pass ports 165, like those in the chambet-B but occupying the plane cf the next lower ports in the inner walls of said vertical passages; and the chambers 157 and 158 contain, respectively, ports 166 and 167 in planes` corresponding i with those of the next lower and lowermost j ports in said inner walls. v -In Fig. 21 and "in Figs. 24-26, inclusive, the valve-plug is shown to be provided about its ends Vand about its wall between each pair of chambers in the plug with circumferential grooves 150a t0 receive packing, the

A pipe 170 l stem ofthe valve 185 meshingwith the gear 15.1 and b earlng'theref form tionary shell 193 f `water-supply pipe 42;

controllable material preferably used for the packing purpose being a heavy grease that will resist melt' under the temperature in the valve, a suilttdle compound being what is known as a aphite-mixture.

he pipe-connections with the valve-device 129 are, for the sake of simplicity and to avoid confusion, indicated by dotted representation in Fig. 1. Each tank is provided in one sidewith an upper port 168 and a lower leads from the upper port in tank WV to the opening 138 in the casing of the valve-device a pipe 171 leads from the'upper port in tank X to the opening 140 a pipe 172 leads from the corresponding port in the tank Y to the valve-device opening 136, and similarly a pipe 173 connects the 'l port 168 with the opening 142 of the valvedevice. A pipe-connection 174 leads from the lower port 169 in the tank W to the opening 139 in 'the valve-device, and the corresponding ports in the-tanks X, Y and Z are respectively connected bypipes 175, 176 and 177 with the openmgs 1'41, 137 and 143 in the l lower part of the valve-device.

Of the vertical series of six openings in the vvalve-casing 130, the second one from the top, namely 145, is connected by a pipe 178 with the suction-side of the pump 54, the dischargeside o f which is connected by a pipe 179 with the uppermost opening 144; the third opening 146 in the series is connected by a pipe 180 with the suction-side of the pump 55, the dischargeside of which is connected by a pipe 181 with the jet-pump 108, and the latter is connected from its lower dischargeendl by a pipe 182 with the fourth opening, 147, in the series a pipe 183 leads the suction-side 184 connects the discharge-side of this pump with the lowermost opening 1 49. A supplemental valve-device 185, the construction of which is shown in Figs. 16 and 17, is connected at the inlet in its lower end by a pi e 186, containing a shut-off valve 187, with t e and a branch-pipe' 188 connects this supplemental valve from its discharge-side with the opening 149. The carries a pinion 189 from the fth opening, 148, to

to the relation of 1 to 2. The purpose of the valve 185 may Abest be ex lained in this 'connection to be that of supp ying cold-water to the circulation when .needed to reduce eX- cessive temperature therein, this supply being through the shut-ofi valve 187. The stem on the upper end of the valveplug 150` ferred construction of which is Figs. 10 and 11: cured to the stem, contains a circumferential series of glass-covered ope s 192 at unidistances apart and isnihlosed 1n asta- 4containing'a display-opening 194 and having a bracket 195 extending illustrated in trally in the indicator-drum,

of the pump 56, and a pipe carries anindicator 190, the pre-- Anupright drum 191, se-

from it by which to fasten it to any'stable support. The shell is surmounted by a removable hood 196 Vcal'ryin an incandescent electric lamp, as indicate to depend cenand adapted to be connected with a source of electric current (not shown). Thus the drum rotates with the valve-plug 150 to display at each quarter-revolution thereof at the point'194 a different character provided on the glass of the respective opening 192 indicating the one of the ing operation has been completed and requiring to be emptied of and refilled with beer to be treated.

The operation is `as follows, 'starting with the valve in the 1st position: The four tanks being iilled with cold water admitted through the pipe 42 and its branches, with the valve 46 closed (being only opened with the valve 43 closed when it is desired to empty the tanks into the sewer), the motor 50 is started to work the centrifugal pumps continuously and drive theshaft 58 intermittently; the steam having meantime been turned on by opening the valve .105. For starting, the swltch 93 is left open and the magnet 72 is tripped by hand to operate the valve-device -129 the first three times for preparing the tanks by heating the water inone to the pasteurizing temperature of about 48 R., and that of another to a lower temperature of, sa about 20 R., leaving the water in the ot er two tanks at the natural temperature'of 10 to. 15 R. at which it is adapted for receiving beer in bottles, with which one of these tanks is the rst to be supplied. l/v'ith the valve in the 1st position. (Figs. 27-27) the circulation, indicated by arrows iu Fig. 1, is as follows: from the top of tank W through pipe 170 to the valve-o ening 138 and into the upper section of t e passa e 132 (Fig. 25), whence it enters the plug-c amber 155 and asses out through a port 159 of that cham er by way of theopening 146 (Fig. 24) into the pipe 180 lunder the pump 55 (Fig. 1), which discharges it through the pipe 181 into the jet-pump 108 where it 4is heated and whence it passes by way of the pipe 182 to the valve-opening 147 leading to the plug-chamber 156 (Fig. 24) thence it iiows into the lower section of the passage 132 25) and out at the opening 139 through pipe 174 back into the tank M( at its port 169. At the same-time the pipe Z to t e opening 142 conducts water from that tank into the sage 134 (Fig. 26), whence it enters the p ugchamber 155 through a by-pass port 163 and passes out through a port 159 to the opening 146 (Fig. 24), from which )the pipe 180 connects with the suctionfside of the pump 55, which also forces that water through the pipe .suction-action of the' upper section ofthe pas Y series of tanks in which the pasteurizhe upper port in the tankV the tank Z, in

come@ 181 into the jet-pump to iiow therefrom thrughthe pipe 182, with the water from tank NV, into the plug-chamber 156, whence a by-pass port 165 (Fig. 24) conducts the same quantity of water that was taken from heated condition back to the same tank through the lower section of the passage 134 (Fig. 26) and through the pipe 177 -leading from that chamber to the lport 1 69 in tank- Z. Under the hand-operation of the magnet 72 the described circulation may be maintained for any length of time (say about to 45 minutes) required to heat the water in tank NV to about 30 R. and that in tank Z to about 20 R.

While the described circulation is taking place, water is being transferred`(incidentally in the starting operation) from the top oftank Y to thetop of tank Z and from the bottom of tank X to the. bottom of tank Y: through pipe 172 and opening 136 into the upper 'section of passage 131 (Fig. 25), thence into plug-chamber 154 'f the and through opening and out through a port 159 and opening 25 145 by way of pipe 178 to the suction-side pump 54, which discharges through pipe 179 into plug-.chamber 153 at vthe opening 144 (Fig. 24),

ber the flow enters the upper section of ,the passage 133 (Fig. 26) and continues'therefrom through the openingl 140 and pipe 171 into the top of tank, X. The pipe 175 takes water from the bottom of tank X to the valve-opening 141 and introduces it into the lower section of the passage 133 (Fig. 26)1 whence it enters the plug-chamber 157 to discharge therefrom through a port 159 and opening 148 to the suction-side of pump 56 through pipe 183, and the pump discharges through the pipe 184 into 'the plug-chamber 158 at 149 (Fig. 24), whence the iow continues through the port 167 into the lower section of the passage 131 137 (Fig. 25) and 169 in tank Y.A The pipe 176 to the port the clutch .by hand operator then trips to permit the shaft 58 to rotate the valveplug through one-eighth of a revolution, thereby bringing 2nd position (Figs. 28-288), in wliichthe circulation takes lace as follows to raise the water in tank to the sterilizing temierature of about 48 R. and that in tank to about 35 R: The course of the water to and from tank W and to andfrorn tank Z remains the saine as described,`with the -valve-device in the first position, exce t 'that its transferorts4 are closed vin t e .2nd position., ile the valve occupies this 'second position, which is maintained until the aforesaid temperatures arereached, the gauntree 48 is run on the track to extend 'over the tank' Y, containing cold water, there to raise a bottle-rack stored therein into position for loading it with baskets and from this chamwhich it continues the valve-device to the' and vset the valve at its and the `rack is thereupon lowered by the gaiintree into the tank. l The operator, now, again 'tri s the clutch by hand, thereby causing t e shaft V58 to rotate the valveplug through the second eighth of a revolution to the 3rd position (Figs. 29-29e), and thereby cause the circulation to ensue as follows, to raise the temperature of the vwater in tank X to about 20 R. and

The disk 96 on the clock arbor 95 has its camsurfaces 99 arranged each to maintain the contact-fingers out of engagement for a period of tyvelvem'inutes andxits camesuraces 97 each to maintain them out of such engagement for a period of eight minutes, so that the circuit is kept open for alternate periods of eight minutes during each of which to maintain the valve-device set for initially heating one tank, by-passing heat into another tank and transferringfro'm one to the other of the other tanks andit is kept open forjintermediate vperiods of twelve minutes, during each of-whlch to maintain the valvedevice set torrnaintaining by the bypass the pasteurizing temperature in one tank 'and raising the other tank to temperature. This automatic action ensues 93 lto'cause the clock-movement to energize the magnet 72 momentarily each time lthe shorter iinger 102 clears the shouldered end of a cam on the disk 96, the resultant energizing of the magnet freeing it to engage and thus cause the constantly rotating motorshaft to turn the shaft 58 through one com- 45' plete revolution, whereby its gear-connection with the valve-plug 150 turns the latter through one-eighthof its complete rotation to bring the ports into the eight different sitions required for handling the four tanks. To avoid confusion on the part of the attendant, the clock should be set for each run of the ap aratus before closing the switch, to begin t e automatic operation with the hands ointing to the full )hour or either twenty or orty minute divisions of the hour, since the circuit-closure occurs at and twelve minutes and the attendant is thus the intervals when away from thea paratus and is not obliged to depend upon tlie sounding'of the alarm by ringing of thegong 62. The gong is only sounded by alternate revolutions of the shaft 58. since during its intermediate revolutions the segmental rack 68 is out of'engagement with the pawl 69, the gearing between the shaft-158' and'g'ear'- 66. being 1 to 2; and the .sounding of the .gong begins with each vtwelve-minutes interval to notify the -atytendant of the condition of the apparatus requiring a supply of beer to bel introduced into a tank for treatment, or that the beer treated in a tank is ready to be removed and supplanted by a fresh charge. In this oonnection'the indicator 190 coperates to display at the opening 194, during the sounding of the alarm, the articular tank ready to be emptied and recliiarged. y

For transferrin `water from the top of tank For holding the pipe 182, opening 147, plugcham Y W to the top o tank Z the course is through pipe 170,v opening 138, upper section of pas- 4 sage 132, chamber 154, opening 145 and pipe 178 to the suction-side of pum 54; l thence through pipe 1479, opening 144, p iig-chamber 153, up er section of passage 134, opening 142 an pipe 173 to .tankZ for raising the temperature therein toI about 30 R. vFor transferring water, from the bottom of tanktemperature 'in the latter to about 28 R., the course is through pipe 177, opening 143, lower section of passage 134, chamber .157, opening 148 and pipe 183 to the suction-side o pump 56; thence through pipe 184, opening 149, plug-'chamber 158, lower section of passage 132, opening139. and pipe 174 to tank W. At the end of this' eight-minutes period of the val e, the rotation of shaft 58 turns it to the 6th position, (Figs. 32-'32 e), in which tank Y is raised to the pasteurizing temperature of 48 R. and tank X is held at that temperature through the by pass flow. In this period beer is laced in tank W by the use of the gauntree, the-temperature of this tank being, as aforesaid, about 28 R. The circulation for these puroses is precisely the same a'sthat descrlbed 1n relation to the 5th position Aof the val-fe and may, therefore, be readily traced withv the aid of that description, bearing in mind, howeV er, that no transfer ,takes lace be-A tween tanksin this position of t e 'val-fe,l wherein it closes the transfer ports.

At the`end of t e last-described eight-minutes eriod, the valve-plug is turned 'to the eight and last position (Figs. 34-348) for raising-tank Z to the pasteurizin temperature and maintaining throu h tlgie byass that temperature in tank Aside fiom 'there beinglno transfer between tanks in this position, t e circulation is the same as that 1n the 7th position and may be traced by the description thereof with the aid of the drawings. ,In this eriod, tank X is suplied` by the use of t e gauntree with beer to .e asteurized.

s will be understood, the succeeding first, second third and fourth positions of the valve-device, as also the'remaining positions, will be attained successively by the automatic action of the mechanism provided for the purpose, throughout the remainder of `90 therun of the apparatus, one tank, durin 'each twelve-minutes period, bein emptie of its contained supply of sterilize beera'nd refilled with a fresh supply of the bottlediarticleto be sterilized. Y

There still remains to be explained the purposeof the lever 78 (Fig. 6): The wheel irr the train 57 which immediately cooperates with the clutch-mechanism, when rotating very rapidly, is `liable to be'too quick for the action of thesolenoid when denergized, be-v cause of residual magnetism. To insure the prompt release, then, of the 77, the clutch-member 86, in the rotation of the hub 88, encounters the lever 78 and turns it, against the resistance of its returning s ring 278," to disconnect the hook ofthe lin 75 from the stud 76 to release the pin 77 and s ring to'efe'ct the uclutching o eration. 110

hen the member 86 has cleared t e lever, the spring 278 actuates the latter sto. again engage the hook with the stud 76 then in position to be so engaged by denergizing ofthe ma net.
